What follows represents the skeleton of a larger thesis and a larger study. The thesis has three integral elements. The first element is historiographic; it involves the question of the conventional boundaries separating the history of science from the history of religion. Breaching these boundaries, at least in the case of the history of Arabic alchemy, is warranted, I argue, not only because of the peculiarities of our historical data, but also because it extends the domain of our explanation and illuminates many otherwise obscure issues. The second element of the thesis is that the Jabirian theory of the ẓāhir and the bāṭin is not grounded in Greek alchemy: in a complex manner, its sources lie rather in Shīʿī metaphysics. The third and final element, which is least developed here, concerns the vicissitudes of the doctrine of the occultum and the manifestum in Latin alchemy. I suggest, tentatively, that the ẓāhir-bāṭin of Jābir ibn Ḥayyān explains the Latin doctrine much better than the ekstrophê theory of the Greek alchemists— which would mean that the roots of the occultum and the manifestum are to be found in Shīʿī metaphysics and not in the Greek alchemical tradition.
According to many accounts, the present day is a time of increasing borderlessness or the breaking down of boundaries. This treatment argues that it is a time when borders are being redefined and redrawn. Examining transnationalism requires a combination of long-term and holistic views. The long-term view brings into question the newness of transnationalism. The holistic view signals that increasing transnationalism in communication, production, consumption and travel is accompanied by the emergence of new borders (as in rising restrictions on migration) and new politics of risk containment (for example, in relation to conflict areas). As some boundaries fade, others emerge that are new and/or internal; moreover, the advantages that accompany the erasure of borders are not evenly distributed. With globalization comes a new dialectics of borders. This may be understood as a process of hierarchical integration, in which integration (the spread of global capitalism and its political influence and cultural radius) fosters borderlessness, while hierarchy imposes new boundaries and forms of stratification.
